Answer:
In midas Civil, for each traffic line lane, multiple influence lines are generated based on wheel spacing.  It is noted that the moving load code is South Africa in the shared image.  For South Africa moving load, 4 influence lines are considered for each traffic line lane.  Hence, the wheel spacing should be lesser than (lane width)/3 = 3300/3 = 1100mm.  In this case, since the spacing was more than this, the error message was displayed.
